Is the RT-N66U w. custom firmware capable of..?

[sandreuta]

Hello.

I was wondering if, after flashing my RT-N66U with DD-WRT/Tomato firmware, will I be able to use it like this:

- the router will have a static IP from my existing network for the WAN port

- 2 wifi SSIDs - one SSID with clients receiving IPs from my network's DHCP server and another SSID with clients receiving IPs from the router's DHCP (other class than my network)

Is this possible?
Thanks in advance.
